What is a ground source heat pump? 

Ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence: the earth. These systems use the earth's relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings.

LMI is a member and an Accredited Installer for IGSHPA (International Group Source Heat Pump Association).

 We are able to work with either existing engineering and designs, or can recommend Monterey Energy Group as a local source for engineering and design services.

Ground Source Heat Pumps offer great benefits:

• Can be a combination heating/cooling and hot water heating system
• Some can save you up to 50% on your water-heating bill by preheating tank water
• Made of mechanical components that are either buried in the ground or located inside the home
• About the same size as a traditional heating/cooling unit
• Pipe carries up to a 50-year warranty
• Can cut energy consumption by 20 to 50% and this is an important feature making it a great partner with photovoltaic systems or homes trying to reach net zero energy consumption. 
• Keep the air warmer in the winter (90 -105 F) and at a more consistent temperature throughout the home, eliminating the hot and cold spots common with other systems
• Very quiet, providing a pleasant environment inside & outside the home
• No noisy fan units to disturb outdoor activities
• No exposed equipment outdoors; children or pets cannot injure themselves or damage exterior units
• No open flame, flammable fuel or potentially dangerous fuel storage tanks

GSHPs offer great savings:

• One of the most efficient residential heating and cooling systems available today
• Heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners
• Save money in operating and maintenance costs

GSHPs are environmentally friendly:

• Conserve natural resources by providing climate control efficiently and thus lowering emissions
• Minimize ozone layer destruction by using factory-sealed refrigeration systems, which will seldom or never have to be recharged
• Uses underground loops to transfer heat, with no external venting and no air pollution
